Hi, Adel romany,

 

We were still unable to reproduce the issue, “Unable to open a PDF document more than one time,” with the loading of PDF on the double-tap event, and it is working as expected. Could you please try the attached sample, which we have modified to reproduce the issue on our end, and let us know whether we have missed out anything while replicating the issue?

First of all, I would like to thank you for your effort and interest,

after trying the attached application, it became clear that the problem was with the property called enablezoompersist which I was set to true but when change it to false the doubletap event work fine and the file change correctly 

Finally, I can only thank you for helping me and wish you a happy life.
